The Benefits of N, P, and K For Plant Plants

Plant growth is not only controlled by internal factors, but is also determined by external factors. One such external factor is the essential nutrient. The essential nutrients are the elements necessary for plant growth. If the element is not available to the plant, then the plant will show symptoms of lack of these elements and plant growth will be disrupted. Based on the amount required, we recognize macro and micro nutrients. Macro nutrients are required for larger amounts of plants (0.5-3% of plant body weight). While micronutrients are required by plants in relatively small amounts (several ppm / parts per million of dry weight).
Macro nutrients include N, P, K, C, H, O, S, Ca, and Mg. While the micro nutrients such as Fe, B, Mn, Cu, Zn, Mo, and Cl. Among the 105 elements that exist on the surface of the earth, it turns out that only 16 elements are absolutely necessary plants to grow and produce. And of those 16 elements, the elements N, P, and K are the necessary plants in large quantities.

A. Element N (Nitrogen)
N element N includes the required elements in the most amount of so-called primary macro nutrients. Generally the Nitrogen element makes up 1-5% of the body weight of the plant.
The N element is absorbed by the plant in the form of ammonium ions (NH4 +) or nitrate ions (NO3-). The source of N elements can be obtained from organic materials, soil minerals, or addition of organic fertilizers.
N functions to prepare amino acids (proteins), nucleic acids, nucleotides, and chlorophyll in plants, so that with the N, the plant will feel the benefits as follows:
  •     Make plants greener
  •     Accelerate plant growth (height, number of tillers, number of branches)
  •     Adding the protein content of the crop.

The Lost Plant Conditions NTanaman's nutrient-deficient elements will show symptoms:
  • The whole plant is pale yellowish (chlorosis) due to lack of chlorophyll
  • Plant growth becomes dwarf, number of tillers or number of branches slightly
  •  The development of the fruit becomes imperfect and often cooks prematurely
  •  In the later stages, the leaves become dry starting from the leaves at the bottom of the plant.
B. Element P (Phosphor)
Element P is also one of the primary macro nutrients so that plants are needed in large quantities to grow and produce. Plants take P elements from the soil in the form of H2PO4- ions. The concentration of P elements in plants ranges from 0.1-0.5% lower than that of N and K.
The existence of P element serves as a storage and energy transfer for all plant metabolism activities, so that with the element P then the plant will feel the benefits as follows:
  • Encourage root growth and establish a good root system
  • Increase the growth of plant tissue that forms the point of plant growth
  • Encouraging the formation of flowers and the maturation of the fruit / seed, thus speeding up the harvest
  • Increase the percentage of the formation of flowers into fruit
  • Compile and stabilize the cell wall, thereby increasing plant resistance against pest attack.

Condition of Rice Plant The shortcomings PTanaman Element that lack of nutrients P will show symptoms:
  • Plant growth becomes dwarfed
  • Root system is less developed
  • Purplish leaves
  • The formation of flowers / fruit / seeds is hampered so that the harvest is late
  • The percentage of the fruit flower decreases because of the imperfect pollination.

C. Element K (Potassium)
In the process of plant growth, element K is one of the primary macro nutrients needed by plants in large quantities as well, in addition to elements of N and P. Element K is absorbed by plants from the soil in the form of K + ions. The content of the K element in plant tissue is about 0.5 to 6% of the dry weight.
The benefits of K for plants are:
  • As an enzyme activator. About 80 types of enzymes whose activations require elements of K.
  • Helps the absorption of water and nutrients from the soil by plants
  • Helps transport assimilation from leaf to plant tissue
Plants lacking nutrients Potassium will show symptoms similar to the lack of N elements, namely: Corn Crop Condition Deficiency Element K
Plant growth becomes dwarfed
 The whole plant is pale yellowish (chlorosis). The difference with the lack of element N, the symptoms of lack of elements K starts from the edge of the leaf so it looks like the letter V upside down.
